Re: [Java-gnome-developer] Gnome Library

[Gabriele E. <nz...@ga...>]

Hi Fernando,
Thanks for all.
I want my application, a GPL P2P Chat with the possibility to live draw (
unfortunatly only in italian ), runs on all system (at the moment I use
Swing but look&feel is awful).
So I want port my application to SWT, but I want to expand the feature of my
application when it runs on gnome for a better system integration.
After your answer I think that I have two possibility:
1) Try compiling java-gnome using the GTK port for Win32 ( I try GIMP on
windows and it's work very well), so it work on
linux, unix and win system; in Italy there are few Mac system !
2) Using only SWT ( I'm not able to exapand SWT, I'm a 23 years old student
of software engineering).
